91. Strephobasis plena (Anth.). 



Tennessee River, Chattanooga (69337) ; Clinch River, above 

 Patton's Ferry (69338). 



S. plena includes as synonyms S. spilbnani, clarkii and cornea of 

 Lea, all from the same region and in the same river system. 



Strephobasis is a mere section of Pleuroeera, and is reducible to 

 some two or three species. 



92. Goniobasis^ proxima (Say). 



Watauga River, Watauga Station (69290), . 



93. Goniobasis proxima symmetrica (Hald.). 



Doe River, Roan Mountain, 2800 to 4000 ft. (69292) ; Rock 

 Creek, Roan Mountain 3500 ft. (69291). 



The same form occurs plentifully around Cranberry, Mitchell Co^ 

 N. C. (Dr. H. Skinner). 



94. Goniobasis laqueata (Say). 



Richland Creek, Belle Mead, near Nashville (69289); South 

 Harpeth River, 6 miles from Bellevue (69348, 69286, 69347) ; Big 

 Harpeth River, near Bellevue (69287, 69288). 



The specimens are not typical, being more like the synonym or vari- 

 ety G. deshayesiana Lea ; but there are at least ten other names, 

 probably referable to the same species, leading terms being plica tula 

 Lea, costulata Lea, cinerella Lea, sparus Lea, cei'ea Lea, rugosa Lea, 

 corrugata Lea, circinata Lea, athleta Anth., glaiica Anth., lyonii 

 Lea, etc. 



95. Anculosa subglobosa Say. 



Nolachucky River, 6 miles southwest of Greeneville (69342) ; 

 Watauga River, below Watauga Station (69343) ; Doe River, 2800 

 4000 ft. (69344). 



96. Anculosa harpethensis Pils. Sp. nov. 



Mr. Pilsbry's description is herewith given : — Shell globose, with 

 very short spire and rounded periphery ; olivaceous brown or yel- 

 lowish, the surface with slight growth lines. Whorls 5, the body 

 whorl very convex, impressed in the umbilical region. Aperture
